C# - Update Panel Stops Working In IE 8 When Site Is Redirected Via A Proxy Server?
Mar 11, 2011
the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'DOCTYPE html PUB'."
I have an Ajax timer that has an interval of 1 second and an update panel on my page. If I leave the page open and never close or refresh I notice that after 6 to 8 hours the timer stops firing. No error messages.......everything just stops. If I refresh the page everything starts working again. Are there any issues I am not aware of when running a page for a long time using the Ajax timer?
We have an updatepanel in our site and there are a number of linkbuttons in it.Please note that the site works fine across all browsers without proxy the proxy changes the url from for instance www.mysite.net to 0-www.mysite.net.edu.net it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is

I have no idea what goes wrong here, it seems that IE can't parse the response?
I have a test page with links that open a panel modally (using AJAXControlToolkit: ModalPopupExtender). I am using an update panel. After clicking any of the links about 10 times, the popup is shown buried under the links (and is not accessible). When I limit the content on the page, the number of times is extended. My thought is that this may be a "data limit" in relation to the update panel, as this works fine when the update panel is removed. I would love to post the code, but this form won't let me. I can certainly send the webform if anyone is interested.
I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.
I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.
I'm using the full-text feature on SQL Server 2008 RC2. Everything had been working well until today. I wanted to change the language for word breakers from Neutral to Slovakia. After I did that, I can't perform full-text search anymore. It simply give me no rows. I even deleted the old full-text catalog and created a new one and populated it, but it still gave no solutions. I tried to query dm_fts_index_keywords_by_document on my table and get only 1 row with a display term END OF FILE.
I'm trying to write some code that checks the number of days between two dates, when I set the date on my IIS7 server to anytime in the future I get the standard "Internet Explorer cannot display the webpage" screen. This happens if I comment out all my date checking code, with todays date it loads with any future date it doesn't. I've tried rerunning IISReset which makes no difference.
So we have three 2008 R2 Servers where two are configured to be web servers (IIS 7.5), and the third a session state server. I have set the SessionState and MachineKey settings in the applications web.config. After I restart the two web servers I can log into one server, then change the IP address to the other server, and I am still logged in. Success.
I can typically log in/out with any user account I want, change the ip address back and forth, and all is well until some random time between 30-60 minutes when I log in to one server, change the IP address, and the new server asks for credentials.
This is the sessionState setting in both web.configs:
The application resides under the default web site, and uses the default application pool. I am using forms authentication with a timeout of 20 minutes. I am not receiving any error events on any of the three servers when this happens, and restarting the two web servers fixes the problem for a while. The two web servers are not clustered per-se, but will be served round-robin via a network device.
When running the ASP.NET Development Server, everything is working fine. However, when I deploy my asp.net application to the production server (IIS 7.0 integrated mode, fresh install), my location tags in my web.config file are being ignored.
Case in point: I'm using forms authentication, and when the user arrives at my login.aspx page, the external css & js files are not being loaded...even though I have specified that those files should be available to all users (auth'd or not). However, once the user is logged in, the files do in fact load.
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
It somethimes happens that, when I use PrinceXML to convert a webpage to a pdf, the local ASP.NET Development Server stops working...It popups the message "ASP.NET Development Server stops has stopped working"
I run a web site with VB.Net and Sql Server, at a web host (so I use one instance of their Sql Server db). I now get this nasty message when trying to access the web site: Column 'kryptotext' does not belong to table tabellen. I have seen this before (but with other columns mentioned), and when I spoke to the tech guys they said that the server gives up after five (or so) invalid requests. The old problems I had were due to the fact that I had used Application variables - at least the problems appeared when I added the variable and diappeared when I deleted them.
This time, I have done very little. I ran a new check when some items of a gridview were databound, and if a condition was ok, then a mail should be sent and an update take place in the db. For now, this will not be true, so the new code doesn't fire, and I have now reverted to the old code anyway. I got htis message this morning, and then it has worked the entire day without me changing the code at all, and now it stopped working again, so to me it seems as if it's either not my code's fault, or I somehow flood the db server with requests (but the web site is new so there are really no users yet). One more thing I have added: I imported the Net.Mail namespace to the baseclass I'm using for the aspx pages, but I can't believe that has anything to do with this.
I asked the tech guys again, and the server has been working the whole day. Here's the web site: [URL] I am able to connect to the admin part of the web site, so it's just the public web site itself that doesn't run. What should I do? Edit: Now, 30 minutes later, it works again. I haven't done anything, in fact I had dinner now.
Can the entire content area of a site be an update panel? I like the idea of the header and navigation not blinking when the content page changes.
Can this be done by putting an update panel as the first element of the content pages or having a update panel wrap the content placeholder in the master page?
I'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.
It works but incredibly slow and whats more on the FF I have the given error:
The state information is invalid for this page and might be corrupted
3 checkboxes with other fields are in the updatePanel
Each field is in dl tag with runat="server>
I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.
Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)
If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.
Oh and I'm using ASP.Net and cant upgrade on this project.
provide the solution to the problem. must achieve the ajax type functionality for the controls of the page displayed within the iframe, the contents(button) withing the iframe are causing complete post back i have used update panel, script manger, on the main page and also on the pae displayed in the iframe even then post back occurs note i check this using the current time of day in the label. here are the codes.
I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.
I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.
I'm working on a simple demo project so that I can learn some things about ASP.NET's AJAX capabilities. My problem is that I can't seem to get an UpdatePanel to work properly with a CheckBox inside of it. Here is the markup I'm using in my .aspx file:
fileupload control is inside a grid, When Ajax is not used its s working correctly, so as wen i use a Update panel, am getting a error in uploading my file to thr database.
